Unibox

How the Zylar Unibox collects replies from every inbox and client into one list, labels them by intent, and lets you reply, assign or push leads to HubSpot.

EARLY ACCESSZylar is rolling out to waitlist members in waves. These docs describe the product as it ships and may change before general availability. Join the waitlist.

The Unibox is one inbox for every reply, across all your mailboxes, campaigns and clients. Replies are labelled by intent, and you can answer them, assign them to a teammate or push the lead to HubSpot without switching accounts. This page explains how the Unibox works and what you can do from it.

One list for every reply

Cold email at volume means many inboxes across many domains, and often many clients. Without a single view, replies get missed. The Unibox collects replies from all inboxes and campaigns into one place.

Interest labels

Zylar labels each reply by intent, so you can work through the ones that matter first:

LabelMeaning
InterestedThe lead wants to talk.
Not nowThe lead isn't ready yet.
OOOAn out-of-office reply.
ReferralThe lead pointed you to someone else.
UnsubscribeThe lead opted out.
BounceThe message bounced.

Labelled replies also drive automation. A reply labelled Interested triggers the reply.interested webhook, and an out-of-office reply triggers reply.ooo. See Webhooks.

What you can do from the Unibox

Reply in place

Answer a reply directly from the Unibox. Your answer goes out from the inbox that sent the original email, so the conversation stays in one thread with one sender. AI can also answer replies and run follow-ups for you. See Sequences.

Assign

Route a lead to a teammate in one click. Teammates are unlimited on every plan, so you can split replies across SDRs or account managers without paying per seat. See Workspaces and roles.

Push to HubSpot

Send interested leads to HubSpot, where they're synced as contacts and deals. You can also post replies to Slack. See Integrations.

Automatic handling

Some replies don't need you at all:

  • Out of office: Zylar reads the return date from the out-of-office reply, pauses the lead and resumes the sequence the day after they're back.
  • Bounces: Zylar removes bad addresses from every sequence.
  • Any reply: The sequence stops for that lead the moment they reply.

Replies across clients

If you run several client workspaces, the Unibox gives you one view across them. Each client's data stays isolated in its own workspace, and roles control who can see what, down to client view-only. See Workspaces and roles.

Replies in your own tools

If your team works in other tools, send replies there too:
